The slip roads are highway links (motorway_link and trunk_link respectively). The problem is that in Mapnik they flow over trunk and primary (proper) respectively instead of under, causing them to "bleed" over (sic). This causes presentation issues, especially when zoomed out.

Most maps in the world tuck slip roads under the main carriageway, and Mapnik used to do that.

Vlad and I have quickly rushed to the location of the crash. We are adding in, with available compatible sources, new details to the crash zone in order to help people who use OpenStreetMap know more about the area, and to advise of any features and landforms that may affect the search and rescue in the next few days.

Please join in to help us.

Our thoughts are for the friends and family of all those on board Germanwings flight 9525.

Quite recently I've noticed blog entries titled "Declaration of Conflicts" on my RSS feed. I hope that OpenStreetMap mappers aren't going into war with each other – that would be terrible, especially as we have done so much to date!

As of now, OSM now has routing on their website as standard: you can plan a simple journey from point A to point B, by car, foot or bicycle. GraphHopper, MapQuest and OSRM are the current routing information suppliers for this module.

If you have version 35.0 of Firefox for Mac, kindly please update the browser to version 35.0.1 to resolve the glitchy-looking rendering issues when you drag the map on OpenStreetMap (Bug entry on Bugzilla).

Other operating systems should update anyway to keep ahead of any vulnerabilities.

Added street light data to the roads of Athens, Barcelona, London and Paris.

Tried to turn Highbury into the densest area mapped globally by adding whatever notable feature there is.

Introduce a proper relation for the London Congestion Charge.

Introduce a proper standard for Greek Provincial Roads.

Mapped Bir Tawil despite facing the technical limitations as others did with Antarctica.

Kicked off a proper attempt at making London transport nodes "public_transport" ready.

And for my next endeavour:

I've started mapping the LEZ in London.

I've started mapping sidewalks in Barcelona and London.

So where next? Would it be nice to fork the OpenStreetMap engine for my roleplay on NationStates? Yes, I know OpenGeofiction but my priorities are different because it involves the real world map as a base and my visions have been bottled up for years.

OpenStreetMap is built by a community of mappers that contribute and maintain data about anything notable, from a stretch of motorway to a humble tree. A majority of what is on the map comes from what they actually saw. What you see is what you get.

The remainder comes from non-copyrighted sources, such as dataset donations from the likes of MapBox to help newbies get started, other ODbL compatible data like nananananananana NaPTAN!... and legislative texts from most countries.

This is why OpenStreetMap is one of the most accurate and up to date maps in the world. When the new Indian State of Telangana came into effect on 2 June 2014, PlaneMad immediately uploaded the necessary boundaries, in the right location. BAM! Just like that.

OpenStreetMap knows that because anyone can contribute to the map, vandalism can happen: however, OpenStreetMap will quickly revert such edits faster than the time it takes to top-up your Oyster card, and deal with them like the Terminator: Hasta la vista! The chances of downloading vandalised data is one in a googol, and even then the end user can catch and correct most vandalism in minutes.

Judging by the screenshots in the BBC article, the Maybe the UK Department for Transport should quit Google and come to us. Once you get used to OpenStreetMap, you'll never see Google in the same way.

The title explains most of this post: given that OpenStreetMap is 10 years old this month, I wonder if anyone still has the original default map style, so I can render today's London in 2004's Mapnik (or its predecessor), preferably in Maperitive?

I've only got Maperitive, so if it isn't possible then can the OSM community help me accomplish this?

I am currently working to get London tube stations ready for the long-term aim of making the network route-able. Alperton and Highbury & Islington are among the first stations to get a stop_area relation prototype. I will plan to publish more details about how I will be doing the mainstream conversion on the wiki later.

Hi, I have a little problem with the Wiki: when I add a new relation to the London Bus Routes list it asks me to solve a CAPTCHA even though I've registered for a long time. Can someone please check which domain name is triggering the CAPTCHA, and whether the whitelist is covering both HTTP and HTTPS versions of OpenStreetMap? I've tested the links in my user page and it seems that the OSM and wiki links are not involved, so could it be one of the tools in the relation template?

I recently added a new postcodes from my recent surveys and corrected some format errors, so I was wondering if any one is still maintaining the OSM source layer in the Postcode map so that I can see how my edits have corrected the errors. Thanks.

Hi, nearly all boundaries in Athens, Greece, suddenly disappeared from the Mapnik map layer. It seems that the new method for rendering administrative boundaries seem to have forgotten relation-based boundaries.

What is the fate for the relation-based boundary standard as opposed to tag-based boundaries?

I recently removed a node in De Beauvoir Town that advertised a flat payable with bitcoins and litecoins. I did a search on Google about the tag and it seems that there may be an overall problem about the use of the tag. Then someone mentioned about people adding their businesses just so that they show up in a website called CoinMap.

To reiterate, the OSM policy regarding places of interests is that we map what we see, or have something that we can verify: that node did not have a shopfront or any visible advert, or a reliable listing as far as I can tell, hence ineligible for inclusion for now.

Update: I have since been able to verify the location as part of a another, and improvements were made: the problem that rose suspicions was it was initially poorly named and poorly located, however, I have struggled to verify a marketing business near Finsbury Park.
